Subject: iommu: Use Functions to set default domain type in
iommu_set_def_domain_type()
Git-commit: adab0b07cbbc73f9fc338e4fc1749714dd093a7c
Patch-mainline: v5.4-rc1
References: bsc#1160320
There are functions now to set the default domain type which
take care of updating other necessary state. Don't open-code
it in iommu_set_def_domain_type() and use those functions
instead.
